Featured Report: Salmon Measurements

A small amount of Fukushima-sourced radio-cesium was found in the July 2011 sample, likely from the initial airborne releases of radioactivity in Spring of 2011. No Fukushima-related radioisotopes were found in the 2012 and 2013 samples.

Our Mission

Our mission is to provide transparent, relevant measurements of radioactivity in our environment for public education and our own research!

Realtime Air Monitoring

The system, located at Etcheverry Hall, monitors airborn radioactivity and supplies data as transparently and quickly as possible, often publishing within an hour. See what radioactive materials are in the air now.

A Guide to RadWatch

Learn about how to read and interpret the data on this site, which is meant to record radiation found in our everyday environment, as well as track any unexpected increases. Get the facts here.

Our mission is to provide transparent data to the public about radiation in our environment.

Ask a question: We'll do our best to answer all queries about radiation in the SF Bay.

We depend on grants and public support to continue publishing this important research.

The RadWatch Sampling Data has been updated to include environmental and reference samples from our most recent measurements of fish, seawater, and even coal. All of this data is cumulatively stored at the Sampling Data Page.

MISSION

Our mission is to provide transparent, relevant measurements of radioactivity in our environment for public education and our own research. Since March 2011, the UC Berkeley Department of Nuclear Engineering has been performing a large range of radiation measurements using state-of-the-art equipment.

DONATE

Donations allow us to maintain and potentially expand our monitoring efforts in the Bay Area and our public outreach efforts in educating the public about nuclear radiation, nuclear technologies, and associated risks.
